Metal Matrix Composite Axial Propulsion Missile Components
Agency / Branch:
DOD / NAVY
The overall objective of the proposed effort is to develop a solid rocket motor case based on metal matrix composites that will maintain or increase the performance of Navy rocket motors and improve compliance with insensitive munitions (IM) requirements. The Phase I effort focused on design trade studies for larger, strategic missiles such as Mk72 and Mk135. The studies compared the performance of a steel case with an MMC case under a fast cook-off scenario using Aerojet's ARCAST analysis code. Design analysis was also performed on various closure methods for MMC cylinders, including secondarily attached and integral closures. The predictions showed the potential for both structural and IM benefits associated with the MMC case designs. Phase II activities will further demonstrate the MMC case technology developed in Phase I and address scaling issues. During Phase III, the technology and methods developed during the prior phases will be implemented into solid rocket motors that are required to be IM compliant.
